Ion—Molecule Reactions in Methane and in Ethane

Ion—molecule reactions in methane, in methane—methane-d4 mixture, and in ethane have been studied up to a pressure of 0.08 Torr in the ion source of the mass spectrometer. Ionization-efficiency curves, appearance potentials, and pressure-dependence studies have allowed the parent—daughter ion relati...

Description
Summary:Ion—molecule reactions in methane, in methane—methane-d4 mixture, and in ethane have been studied up to a pressure of 0.08 Torr in the ion source of the mass spectrometer. Ionization-efficiency curves, appearance potentials, and pressure-dependence studies have allowed the parent—daughter ion relationship and the cross sections of the pertinent reactions to be determined.
